To all whom may amine-m Be it known that l, uinna'r .l inrcoiin, a citizen of the Jnitml States of Anioricm residing at Bay City, in the County of Illay and State 01"? lvliehigan, have invented can to in now' and 'usoi'ul Improvements in can burctcrs, of which the following is a specifi- -at1on, reference being had therein to the, accompanying drawing This invention relate to caroureters and the primary obit-ct of my inv 511E101) is to provide a carburctor wherein part of the exhaust hf a manifold from an internal coinbustion engine may be utilized to assist in vaporizing gnsoleno or other fuel lct into the carbinotor.

nnothcr ohject of my invention is to pro \ltlC a earhnmter Whcrein the exhaust oi an engine may be utilized tor heating Walls of a cailnncter, so that air and fuel admit ted to the carburetor Will he in better condition, when coininingled for explosive purposes in the cylinders of an engine.

A Further object of my invention is to provide a carburetor ot' the above type consisting' of comparatively tow parts that are inexpensive to 1nanutzmture durable, easy to assemble, and" highly ellicient in connection with an internal combustion engine The above and othor o icts arc attainod by a mechaninl (onstructirni that will he hereinafter specifically described and than olaimcd andv retiiercncc willv non he had to tho drawin 9;s wherein Figure l a plan of the carburetor. and

Fig. 2 a longitudinal soe'ional 'vicw oi the same. i

In the drawings, 1 denotes a iloat chain her having a drain noel: Q and a detachable cover or can 3, said cover hav ng; an inlet orifice {t in connnunication with a fuel supply pipe or conduit 5. lVithin the chainbor 1 is a float 6 provided with a needle valve '2' movable to and from the orifice 4 to automatically regulate the intake of fuel to the chamber 1 and the lo al of fuel therein. The elements just described are of a conventional form common in great many carburetors.

A Wall oi the float chamber 1 isiintogral with a wall 8 of an elbow 9 constituting a carhnretcr body. The lateral portion '10 oi? the elbow 9 i in a plane with the float chainher 1 and this l teral' portion of the elbow constitutes the air inlet to the carburetor body, and supply of air controlled by a throttle or buitcr upon a rock shatt medium oi a maid; 1,) and arod to he at 6i tached to tho intake manifold of an i1 nal ('(lllllJllSilOll angina in the usual and it t oi known manner. and the walls of thcnlhow or carburter body 9 arc chambered or ho lowed out. as at 15; whereby the elbow on carburetor will'huvc outer and inncrwvalls with an inlcrvcnii'm' spaeo or chamber adapt ed to i'cccivothc exhaust from the inani oli oi? an internal mn'nlmstion engine so that the inner wall oi the carbui'ctor hotly or all 7 will be heated. For this purpose tho la portion it) o tho 'arhnrcter has coiniccti 153 and 17. either ono of which may on conan inter-- nvctcd to the exhaust manifold ol pal mmbustii'in engine sothat tho H i mv irculate or pass through the chainb ot the elbow o carburetor body.

The outer Q c of the elbow or carbon body 9 contiguous to the intcgral Wall 0'" float chamber has an inner 'vii rtieal disioscd cnlaroonnmt l9 orovided with port 2). a well 21 and a restricted port establishing: eominunieation between Noll 21 and the port The lo'a'cr e110 the port l op in a stui'lin ho an a noodle valv ablc to and l'rom the restricted port 'Tl'io l i so coinmunicatos with tho thaw cha through a la al port 25, consortia the fuel within tho noat chamber 1, Us l id its le cl n'ii'hin thc well of tho niilai" meat 19 and tho supply of tool thro li the null may he regulated by the ni ctlln Yalvo 'lhc \vcll 521 is in commonication \i' h the chamber of tho clboyv or carhu" body 9 thron h the medium of an an tgnli .7 disposed or upwardly tliracted port adapted to emit engine xhaust and elect fuel from the Well it. As the exhaust iliroin tho manifold of an internal coniluistiz nine is under pressure, there will he exhaust gasos from the port 26 tend lift thc contents of the Well 21 and coffinovate h the usual suction fron'i i manifold oi an Q and flllpl no cn 'ine hnat d chmtwd into the chanihr tho oarhuretor sufficient to hem into the Iarlnnrotcr anl zsify One embodiment of my invention has been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scopeof the appended claims.

What I claim is 1. A'carbureter having the walls thereof chambered ,-and adapted; for communication with. theie'xhaust manifold of an internal combustion engine, a float chamber forming partofseid earb lreter, and an enlargement in said eyhni'etdr provided with a Well in communie on With said float chamber and with the-clib linbers in the walls of said carburetereo, that the'exhaust gases assist in providing-aneificient explosive mixture.

' 2. A earbureter having the walls thereof chambered xand adapted to receive the exhaust vgases from an internal combustion engine, afloat ehamber, an enlargement in said carbureterprovided with a Well comlnllIllCat with the chambers in the earbureter we sa;'ncl also with said float chamber, and means controlling'the communication between said float chamber end the well i of said-enlargement.

3. A carbureter having the walls thereof provided with chambers adapted to receive exhaust gases 0.1: an internal combustion engine, a float eha-n'iber, en enlargement in said eerbureter having a Well, said enlargement having ports establishing communication between said Well and said float chamber, said enlargement having an singularly disposed and upwardly directed port to establish COXIL munication between the well of said enlargement, and the chambers of the carburetor alls, and means controlling the communi" cation between the Well of said enLai'gement ALBERT ARNOLD,
